Patented Feb. Z, 1932 lUNITEI) STATES PATENT OFFICE HENRY A.'WISE WOOD, 0F .NEW YORK, N.

Y., ASSIGNOR T0 WOOD NEWSPAPER MA- CHINERY CORPORATION, 0F NEW YORK, N. Y., A CORPORATION OF VIRGINIA WEB CHANGE DEVICE Application led July 7 1925, Serial No. 42,7061. Renewed October 2, 1928.

This invention relates to the attachment of the leading end of the web of a new web roll to the expiring end of the web of a nearly exhausted roll so as to feed a web to a print- Lt5 ing press continuously without stopping the operation of the latter; and without slowing it up while the webs are being connected.

The principal objects of the invention are to locate the fresh and running rolls in such position with respect to the path of the webthat Ithe web will move closer and closer to the fresh or spare roll merely by the change of the web path due to the decrease in size of the running roll; to provide for setting the roll propelling means for the new web rol'l at the proper time by handY into contact with the new roll and at the same time bringing a device for del'ecting the running web out of its normal path into a position adjacent to the new web roll ready for action; to provide means whereby these two functions will be performed by the operation of the same lever or other starting device; to provide means whereby the movement of the new web roll in its circular path wil-l bring it into contact with the running web as deflected by said deflect-ing device so that the next ytime the pasted portion thereon moves `around into contact with the new web it will be pasted thereto; to provide means for automatically puncturing the papern ofthe old web, and applying a brake to the old or running roll spindle so to sever the web by these two operations, and for automatically stopping the rotation of the reel lcarrying the several web rolls including the expired stub and the new roll when the latter gets to its running position. The invention also involves improvements in the means for accomplishing these several results,including the operating handle and connected mechanism for 'lowering the roll propelling tapes into contact with the fresh web roll to start it into rotation and bringing the web deflecting device into a position adjacent thereto; means in position to be engaged by the new web roll when it moves up to past-ing or spliing position for stopping at the proper time the rotation of the reel on which the said web roll is mounted, applying the brake to the expiring roll, actuating the puncturing device which startsy theV separation of the old web from its stud, and connecting up the other operating mechanism with the driving shaft and disconnecting the same therefrom. Other .ob-

jects and advantages'of the invention will y appear hereinafter.

For the purpose of indicating the general action of the machine before describin ,the mechanism and the operation in detail will describe the first eight figures further.

It will be understood that the running web rollA, the fresh'web roll B which are both on the same side of the web W, and the third web roll C which is to become the next fresh roll, are mounted on a reel 58 which turns about a central shaft 120 as will appear. The fresh web roll A in Fig. 1 is delivering the web W to the press past the roll B over a spring-pressed idle guide roll 51 and a web control roll 52 operated positively from the press. The web is propelled by a series of feeding belts 53.' The web travels uniformly and passes into Contact with a brush 54 or, as I have called it, a deflecting device. This figure shows the normal path of this web during lthe run, the brush constituting merely a guide for it at this time. In this figure also are shown the propelling means in the form of tapes 56 for rotating the fresh web roll B on itsown axis.

In Fig. 2 nothing is changed except that the paste-spots P have been applied to the roll B and the running roll A is becoming exhausted.

In Fig. 3 the web has approached toward the fresh roll by reason solely of the decrease in size of the running roll A. Now the fresh roll propelling tapes 56 are lowered into contact with the fresh roll to start it into rotation, and the brush 54 is moved down so that it deflects the web out of its normal path and brings its deflected point nearest the fresh web roll, except for a slight change which will be mentioned later. It is to be noted that where the web is deiiected from a straight path at this point it is at a point located about where it would come into tangency to the fresh web roll.

' Now in Fig. 4 the running roll is almost exhausted and ready for the operation; the

fresh roll now rotating in the direction of hausted roll down along the feeding belts 53 butit is still under their control.

In Fig. 5 the roll B has not moved substantially but the brush 54 has been shifted on a pivot toward the fresh web roll, so as to bring the running web into contact with the roll B. In Fig. 6 the spots of paste P have rotated around into contact with the old web and the web is spliced. A double web is therefore shown for a short distance along the course of the running web. Furthermore, a knife 57 has been brought against the web near one edge and started its sepa# ration from the stub. Although not indicated on this figure, a lbrake is applied to this stub at this time to assist in the severing operation.

Now Fig. 7 shows the first step in the realso raised to its original position. Also the reel hals-moved to brlng the fresh roll B over into contact with the belts 53 and the eX- hausted stub A out of contact with them.

Fig. 8 merelyvl shows the position of the parts when the reel has moved around far enough so that the new roll B isnow in the position which the original runnin roll A previously occupied or nearly so, an the last mounted roll C is moving up into a position for its web to be spliced to the exhausted web at the proper time. Now the'reel continues to rotate by power-,until the parts are back in position as shown in Fig. 1 and then 'the power is automatically cut off from the reel to leave it in that position while the running roll which, it is to benoticed is marked A and notB in that figure, supplies its web Y to the press.

scribed above.

It will be understood that a good deal of the mechanism above described is connected with and operated by the press. For example, a bevel gear 60 (Fig. 12) on the shaft the main part of the press and operated continuously at such a rate that its surface rotates at web. speed. The other end of the shaft is provided with a sprocket wheel which drives a chain 62 connected with a sprocket wheel on a shaft 61 for driving. the latter. On this shaft 61 are pulleys 63 on which are the feeding belts 53. The shaft 61 also, bymeans of sprocket wheel, drives another chain"64' driving a sprocket wheel Oo-n a shaft 66. On this shaft are two pulleys 67 which drive the fresh roll propelling tapes 56. uThese propelling tapes also pass over a pair of rolls 68 mounted to freely rotate on a shaft mountedin slots in hubs 69 on arms 70. The arms are pivoted on `the shaft 66 and swing about the same in the manner de- The rolls 68are adjustable by meansrof adjusting screws 71 to vary the tension on the propelling tapes. L

Carried by the frame of the machine'is a crossxshaft 72. This is provided with a series of arms 7 3 which .carry depending links 74 having elongated slots 75. These slots receive rods 76 on the arms 70. ThereforeI when in the position shown in Fig. 9, they `hold these arms up so that the propelling tapes are out of the way as in Figs. 1 and 2. When in the position shown in Fig. 14 they let them down Iand enable the propelling' tapes to contact with the new web roll B (see Fig.

Also fixed on the'shaft 72 is an arm 78 connected by a link 79. with an arm 80 pivoted on a cam shaft 81. 'This arm 80 has a pawl 82 thereon for co-operating with a tooth 83 projecting from a disc fixed/to the shaft 81 toV turn the shaft'through a small arc when the feeding tapes are lowered. On the shaft 72Lthere is pivoted van operating handle 15v having a springpressed rod 16, the endof which is adapted to en age in either one of two notches in a disc 17. Xedon the shaft 7 2. Thisspring-pressed rod'16 is operated by handle grip 18 in connection with the grip 19 on the handle 15 so that the shaft 72 can be turned and with it the propelling tapes raised or lowered and the pawl 82 operated for the purpose of turning the shaft 81 slightly by hand when these belts are operated.

LThe shaft 61 is provided with a worm operating a worm wheel 84 on a shaft 85 and therefore through bevel gears 86 constantly drive a friction clutch section 42 loose on j the cam shaft 81.

On this shaft 81 are two cams 88 each having a groove 89 provided with a depression 90. -ln this cam groove operates a roller91 on an arm 92l fixed on a 'shaft 93 and having an arm 94 projecting therefrom at each end. On each arm 94 is a stud 95 carrying a block 96 which is located in a slot 97 on a slide 98.

This slide has a pair of guiding surfaces which receive between them a vertical guide 99 on a stationary bracket 100 on the frame. Therefore the oscillation of the arm 94 causes the slide 98 to move up and down on this guide.

The slide carries a pivot stud 101 which has fastened to it and swinging with it an angle iron frame 102 which carries the brush 54 previously referred to. Also fixed with respect tothe stud 101 is an arm 103 which carries a cam roller 104. On this swinging arm 103 is a poppet 105 carrying an adjustable spring pressed rod 106, the opposite end of which is carried by a projecting arm 107 on the slide 98. This .spring pressed rod 106 presses the swinging arm forwardly and holds the roller104 against a stationaryy cam 108 on the fixedvbracket 100. It will be seen therefore that the angular position of the brush 54depends on the elevation of the slide 98 with relation to the cam 108.

The section 42 of the clutch on the shaft 81 turns freely thereon. The magnetic field 44 of the clutch is keyed to the cam shaft 81. When current from any suitable source is carried through the magnetic field of this clutch,

ythe two clutch parts 42 and 44 willy been# gaged and the cam shaft 81 will rotate part way around. ,On account of the electricalv means illustrated, the circuit for the magnetic clutch and other electrical features can bev supplied by a generator 45 or any other source Aof power. From the source ofpower a line metallic ring 20. These rings are mounted onl the shaft 81 but insulated from each other. It will be "seen, therefore, that when this circuit is closed by the engaging of two contacts 21 the circuit will be completed to these two rings, and supply current through a pair of wires 22 to the magnetic elements in the clutch ,and cause the shaft 81 to rotate from the driving shaft 85. The collector ring 49 has a projecting insulated element 23 which,

after the cam shaft is rotated a slight distance, will disconnect the collecting ring from a brush 24 connected with a wire 25. When the projection 23 allows the spring-pressed brush 24to engage the metallic surface of the collector ring 49 it establishes a circuit through this wire 25 and the collecting ring, from the dynamo or the like 45, to a circuit breaker 26 through a 4switch 27 which we will suppose to be closed at the present time, and' a switch 28 back to the dynamo. When these switches are both closed, the circuit breaker 26 will act on a lever 29 to close the. main circuit 46 at 2l, and thereby operate the shaft `81 by power. The lever 29 alsol closes contacts 40 to short circuit both switches 27 and 28. When the cam shaft 8l has completed a certain angle of rotation the brush 24 rides up on the surface 23 which is insulated from .the rest of the collector ring, thereby releasing the lever 29 and breaking the main circuit 46 at the point 2l. This stops the cam shaft.

On Fig. 26 l have shown all the electrical connections. lt will be noticed that here iS a driving motor 3() connected with the dynamo 45 and the line 46 by a circuit represented by a dot-and-dash line which is broken at two points by hand switch 31 and magnetically operated switch 32. A circuit breaker 33 operates the latter at certain times upon the closing of the switch 28. When this switch closes the circuit breaker is energized and the circuit to the motor is interrupted automati cally.

Ihave also shown a dotted line circuit con nected with a regionen the collector 49, which region is interrupted by insulating sections 34 separated from each other so that once during each rotation of the cam shaft the circuit from the line 46 is connected through the space between these insulating sections and the dotted line circuit to a solenoid 35 and back to thefline 46. This operates lthe cutter 57 through a lever or bell-crank 36, pivoted on a center on a frame 119 of the reel 58 which supports the rolls A, B and C. One arm of this bell-crank is connected by cable 37 with a roll v38 on a shaft 39 on which the cutter 57 vis located. A spring 39 on this shaft 39 holds the cutter back against the action of the lcable 37 which is pulled out by the solenoid to swing the cutter as shown in Fig. 25.

On the reel frame 119 is located a shaft 120 which carries the reel 58. This reel comprises three -sets of arms which support the studs 122 of the three web rolls A, B and C. On the shaft 120 is a gear 123 operated by a worm 124 on a shaft 125 driven by the motor 30 for the purpose of rotating the reel 58.

Each of the sets of arms for supporting a roll is provided at one end of the reel with a brake disc 127 fixed on the web roll `stud 122 which is supported by the arm. lThere is a brake-band 128 .for each disc. Each brakeband is connected at one end through a poppet 129 adjustably with a platel 130' which is fixed to the arm of the reel. The other end of each brake-band is pivotally connected with a lever 131 which yhas a weight 132. The weight operates at certain times to pull the lever around and tighten the brake-band as appears in Fig. 24. This lever 131 is provided with two hooks 133 adapted to be engaged bya double latch 134 pivoted on the plate 130. Thislatch 134 has a projecting end 135 adapted to be engaged by a roll 136 on a third arm 137 on the lever or bell-crank 36 for the purpose of releasing the lever 131 from the position shown in Fig. 23 and allowing the weight 1 32 to move over into the position to apply the brake as shown in Fig. 24. This occurs when the solenoid acts to operate the knife 57. It will be noticed that there is one of these on each of the three arms of the reel', althoughthere is only one solenoid. The action just described is arranged to take place when the center on which the latch 134 turns ,comes around to register with the center on which the lever 36 turns.

On each of the web roll studs at one end is an arm 140 having a roller 141. It is this roller that engages the switch 27 and closes it when the reel moves around to the position shown in Fig. 26. This occurs after the surface of the web roll itself engages thearm of the switch 28 to close that. A stationary bracket 145 is provided for supporting the switches27 and 28 and the cutter shaft 39.

Operation Starting with the parts in the position shown in Fig. 1 it will, of course be understood that the fresh roll propelling tapes and the web feeding belts are being operated continuously, although the former are lifted up out of the wayand perform no function. The web, of course, isrunning from the running roll A to the guide roll 51 past the fresh roll B and into the press, the reel is not rotat-ing nor the roll B. The cam shaft 81 also' is not rotating.

Now as the web runs and the running roll grows smaller, the web gradually approaches the fresh roll. When the running roll A gets quite small, as shown in Figs. 2 and 3, the operator first pastes the spots P on the roll B and then he lowers the handle 15 so as to lock it inits lowermost position. vThis lowers the propelling tapes on the new roll B.

When the operating handle 15 is lowered as stated, it not only operates the propelling tapes 56 but it moves the link 79 forward so that the pawl 82 will engage the tooth 83 and turn the crank shaft a short distance from the position shown in Fig. 9 to that shown in Fig. 14, so 'that-the brush24 will move off the insulated element 23 and rest against the collector ring 49.. This rotates the cams 88 from the line d to the line a in Fig. 11. These cams thus act to cause the mechanism'carrying the brush to lower the latter along its opposite guides from the position shown in Fig. 9 to that shown in Fig. 14. This is accomplished by the weight of thc slides 98 and brush and the shape of the cam grooves. These slides 98, one en each side of the machine, move down at first without changing the angular position 1Aof the brush. The rollers 104 on the arms 103 rest on the high part of the cams 108, thereby keeping the brush drawn back as shown in Figs. 4 and 16. This is as far asthe shaft is turned by the handle 15, and is indicated by the line a in Fig. 11, that is, the rollers 91 are in ythat part of the cam grooves 89 and have not yet dropped into the recesses or depressions 90. The operator also closes the hand switch 31. As the switch 32is closed by a spring, the motor 30 will bc started and the reel will commence to rotate to carry the three rolls around slowly. The

-ing' on its own axis and when the arm 140 on its stud has rotated around to the position shown in Fig. 26, at which time the paste spotf Pis practically in pasting position, th switch 2T will be closed by the roller 141. Now a circuit is completed through this switch and through the circuit breaker 26 whi'ch forms a f contact at 21 and completes the circuit 46 so as to start the cam shaft 81 by power. The contacts are also closed at that same time and the two switches 27 and 28 thus cut out or short-circuited so that the further, rotation of the arm 140 will not affect these conditions.

The rotation of the cam shaft 81 by connection of the clutch sections 42 and 44 .A through the establishment of the circuit 46 r has for its first effect the bringing of the cam roll 91` i-nto the depression 90 in the cam, passing from the line a to the line b in Fig. 11. This results in lowering the arm 94 slightly,

' so as to bring the cam roll 104 the high .part of its ca'm 108 and swinging the brush f from the position shown in Figs. V4 and 16 to that shown in Figsf and 17 so as to bring the web and the surface of the roll Bv into contact. The continued motion of the twO cams between the lines b and c causes no change in the .position of the brush so that the brush will be sure to press the web against. the pasted edge of the web roll B and that pasted edge will travel well into the feeding mechanism of the press. This brush is designed to yield tol the irregularities of the web roll and insure the pasting of the web all the way across.

When the cams have rotatedto the point marked 0, Fig. 11, the cutting oif of the expiring web takes place (Fig. 6). The spaces between the ends of the insulating ring 34 on the collector 35 permits the brush 43 to contact with the metallic surface of the collector and the current to fiow from the generator 45 through the brush 48, collector ring 49, and dotted' line circuit to energize theP solenoid 35. This operates the puncturing blade 57 from the position shown in full lines in Fig. 25 to that shown in dotted lines, so that it will start a cut'in the edge of the paper. At the same time the operation of the bell crank 36 by the solenoid acts to disengage the latch 134 from the tooth 133 ofthe lever 131 pivoted on the'arm of the reel carrying the expiring web roll. That welght 132 comes down and applies a brake to the spindle'of that roll. By these two actions and the pressure of the brush `54 on the web, the latter is severed from the expiring web roll stub.

After' the severing blade 57 has operated, it A is restored to its original position by the spring 39a as stated. Atfthis time the operator raises the handle 15 thus taking the propelling tapes off the roll and restoring the pawl 82 to the position shown in Fig. 9.

The continued rotation of the cam 88 from c to Z brings the roller 91 out of the cam. This raises the varm 94 and restores the brushes-to theoriginal position as indicated in Fig. 7. When the point d is reached the circuit is broken by the insulated section 23 0n the collector ring 49 and the circuit can-4 notjbe re-established until the cam shaft is moved from the pbsition d to the position a and the insulation 23v moved away, from the brush 24 so the circuit breaker 26 can be energized. This rotationhas to be performed by hand through the handle, 15 as above stated. The breakingof the circuit at 23 also deenergizes the circuit breaker 33 and allows the switch 32 to be c losed by the action of its spring thus starting the reel to rotate again to bring up afresh roll C nearly to pasting position.

It will be seen, therefore, that the whole machine is operated at web speed when the' splicing is being done, and is started merely by the depression of the operating handle 15.r

and the closing of the hand switch 31. The

whole operation is performed while the web* is moving atweb speed and the operator does ,I

not have to perform any function at all in order td`stop the machine, stop the reel, or to bring any or all of the parts to their normal running position ready for the next'splicing operation. The action is not only automatic, but quick and1accurate.and on accountu of the i construction and operation of the parts they cannot be operated at the wrong time by any ordinary tampering with the machine.

In view of the number of operations the machine performs it is a comparatively simple machine in construction and operation.

Although I have illustrated and described only one form of the invention, I am aware of the fact that many modifications` can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.
